As shown in FIG. 1 to FIG. 4, the automobile identification system of the present invention may be applied to an automobile C, including at least one first fingerprint sensor F1, at least one second fingerprint sensor F2, a database 20, and a processor 10. Each of the first fingerprint sensors F1 is disposed on an exterior of the automobile C to generate a first fingerprint image I1. Each of the second fingerprint sensors F2 is disposed on an interior of the automobile C to generate a second fingerprint image I2. The database 20 is disposed on the interior of the automobile C and is storing at least one primary reference fingerprint image PI. The processor 10 is disposed on the interior of the automobile C and electrically connected to the database 20, each of the first fingerprint sensors F1, and each of the second fingerprint sensors F2 to receive the first fingerprint image I1, the second fingerprint image I2, and the primary reference fingerprint image PI. When the processor 10 determines that the first fingerprint image I1 matches the primary reference fingerprint image PI, the processor 10 obtains a pass authentication and makes a door of the automobile C open. When the processor 10 determines that the second fingerprint image I2 matches the primary reference fingerprint image PI, the processor 10 obtains a use authentication and makes an engine of the automobile C activate. Through a dual determination by the processor 10, it may be confirmed whether the person who attempts to enter the automobile C is a driver without the need for a conventional key to open the door of the automobile C or activate the automobile C.

It should be noted that the exterior and interior of the automobile C are distinguished based on the door; that is, the side of the door close to the external environment is the exterior of the automobile C, and the side of the door close to the seat is the interior of the automobile C. The above is for illustrative purposes only and is not intended to limit the scope of the present invention.

In one embodiment, the first fingerprint sensor F1 may be disposed on the door of the automobile as shown in FIG. 2; in another embodiment, the first fingerprint sensor F1 may be disposed on the handle H′ of the door of the automobile as shown in FIG. 3. The first fingerprint sensor F1 may also be other preferable positions, and is only disposed on the exterior of the automobile C, but is not limited to the scope of the present invention. In addition, the plurality of second fingerprint sensors F2 may be respectively disposed near the steering wheel, the control lever, and the multimedia player as shown in FIG. 4; it is also possible to have other preferable positions and is not limited to the scope of the present invention.

(2) When the processor 10 determines that the first fingerprint image I1 matches the primary reference fingerprint image PI but the second fingerprint image I2 does not match the primary reference fingerprint image PI, the processor 10 obtains the pass authentication without obtaining the use authentication. Each of the second fingerprint sensors F2 may not sense the person who has entered the automobile C. Therefore, the person who has entered the automobile C places the finger on the second fingerprint sensor F2 again, and the second fingerprint sensor restarts sensing fingerprint images. (3) When the processor 10 determines that the first fingerprint image I1 matches the primary reference fingerprint image PI and the second fingerprint image I2 matches the primary reference fingerprint image PI, the processor 10 obtains the pass authentication and the use authentication, that is, confirming that the person who attempts to enter the automobile C is the driver.

In addition, the automobile identification system of the present invention further includes a positioning element 30, a peripheral element 40, a human-machine interface 50 having a wireless transceiver RT, and an external electronic device. The positioning element 30, the peripheral element 40, the human-machine interface 50 having a wireless transceiver RT are all disposed on the interior of the automobile C and electrically connected to the processor 10; the external electronic device is wirelessly connected to the wireless transceiver RT; Wherein, wireless connections include the Internet, Wi-Fi, WiMax (Worldwide Interoperability for Microwave Access), ZigBee, Bluetooth, NB-IoT (Narrow Band IoT), or LoRa (Long Range). It may be possible to have other wireless connections and is not limited to the scope of the present invention.

After obtaining the pass authentication and the use authentication, the processor 10 sends a start signal to make the positioning element 30 operate; the positioning element 30 performs positioning for the automobile C and establishes a map according to the surrounding environment of automobile C; the positioning element 30 may also acquire the information on the weather and temperature of the place where the automobile C is located, and the driver may better understand the environment and traffic; the driver controls the operation of the peripheral element 40 through the human-machine interface 50. Alternatively, the driver may send a control signal to the wireless transceiver RT through an external electronic device, thus transmitting a control signal to the processor 10; the processor 10 controls the operation of the peripheral element 40 according to the control signal. Meanwhile, the processor 10 records the setting of the peripheral element 40 which is then stored as the user information UI of the database 20; when the driver is sensed by the first fingerprint sensor F1 and the second fingerprint sensor F2 again, the processor 10 may extract the user information UI from the database 20 according to the first fingerprint image I1 and the second fingerprint image I2; then, the processor 10 displays the user information UI on the human-machine interface 50.

Herein, the operational mechanism of the processor 10, the secondary reference fingerprint image SI, each of the first fingerprint sensors F1, and each of the second fingerprint sensors F2 is described in detail as follows: (1) When the processor 10 determines that the first fingerprint image I1 does not match one of the plurality of secondary reference fingerprint images SI, the processor 10 does not obtain the pass authentication and makes the door of the automobile C locked, meaning that the person who attempts to enter the automobile C is not the user authorized by the driver to use the automobile C. (2) When the processor 10 determines that the first fingerprint image I1 matches one of the plurality of secondary reference fingerprint images SI but the second fingerprint image I2 does not match one of the plurality of secondary reference fingerprint images SI, the processor 10 obtains the pass authentication without obtaining the authorized use authentication and each of the second fingerprint sensor F2 may not sense the person who has entered the automobile C. Therefore, the person who has entered the automobile C has placed his finger on the second fingerprint sensor F2 again; alternatively, the processor 10 does not immediately find the secondary reference fingerprint image SI that matches the person who attempts to enter the automobile C, so the processor 10 restarts searching for another frame of the plurality of secondary reference fingerprint images SI in the database 20. (3) when the processor 10 determines that the first fingerprint image I1 and the second fingerprint image I2 both match one of the plurality of secondary reference fingerprint images SI, the processor 10 obtains the pass authentication and the use authentication, confirming that the person who attempts to enter the automobile C is the person authorized by the driver to use the automobile C; the processor 10 opens the door of the automobile C and activates the engine of the automobile C.

Similarly, when the processor 10 determines that the first fingerprint image I1 and the second fingerprint image I2 both match one of the plurality of secondary reference fingerprint images SI, the processor 10 obtains the pass authentication and the use authentication, confirming that the person who attempts to enter the automobile C is the user authorized by the driver to use the automobile C; after obtaining the pass authentication and the use authentication, the processor 10 sends a start signal to make the positioning element 30 operate; the positioning element 30 performs positioning for the automobile C and establishes a map according to the surrounding environment of automobile C; the positioning element 30 may also acquire the information on the weather and temperature of the place where the automobile C is located, and the user may better understand the environment and traffic; the user controls the operation of the peripheral element 40 through the human-machine interface 50; alternatively, the user may send a control signal to the wireless transceiver RT through an external electronic device, thus transmitting a control signal to the processor 10; the processor 10 controls the operation of the peripheral element 40 according to the control signal. Meanwhile, the processor 10 records the setting of the peripheral element 40 which is then stored as the user information UI of the database 20; when the user is sensed by the first fingerprint sensor F1 and the second fingerprint sensor F2 again, the processor 10 may extract the user information UI from the database 20 according to the first fingerprint image I1 and the second fingerprint image 12; then, the processor 10 displays the user information UI on the human-machine interface 50.

Please refer to FIG. 5 which depicts a block diagram of the automobile identification system according to the second embodiment of the present invention. As shown in FIG. 5, the main difference between the second embodiment and the first embodiment lies in the fact that the processor 10 has an owner mode O and a visitor mode V and the database 20 stores at least one frame of the first reference image R1 and at least one frame of the second reference image R2; the configuration of the rest of the elements are the same as that of the first embodiment, and thus the description of the configuration of the same elements shall be omitted herein.

(2) when the processor 10 obtains the pass authentication but determines that the second fingerprint image I2 does not match the first reference image R1 or the second reference image R2, the processor 10 obtains the pass authentication without obtaining the first access right and the second access right. Each of the second fingerprint sensors F2 may not sense the person who has entered the automobile C. Therefore, the person who has entered the automobile C places the finger on the second fingerprint sensor F2 again. (3) When the processor 10 obtains the pass authentication and determines that the second fingerprint image I2 matches the first reference image R1, the processor 10 obtains the first access right and has access to the owner mode O and the processor 10 makes the automobile C travel at a high speed or at a low speed.

Alternatively, the driver may send a control signal to the wireless transceiver RT through an external electronic device, thus transmitting a control signal to the processor 10; the processor 10 controls the operation of the peripheral element 40 according to the control signal. Meanwhile, the processor 10 records the setting of the peripheral element 40 which is then stored in the database 20; when the driver is sensed by the first fingerprint sensor F1 and the second fingerprint sensor F2 again, the processor 10 may extract the setting of the peripheral elements 40 stored in the database 20 according to the first fingerprint image I1 and the second fingerprint image 12; then, the processor 10 displays the user information UI on the human-machine interface 50.

Moreover, the object side surface and the image side surface from the first lens 11 to the sixth lens 17 may be aspheric, which may obtain more control variables. Apart from eliminating the aberration, the number of lenses used may be reduced compared with that of traditional lenses used made by glass. Thus, the total height of the camera lens may be reduced effectively.

Furthermore, in the camera lens of the present invention, when the surface of the lens is a convex surface, the surface of the lens adjacent to the optical axis is convex in principle.

Hence, it not only contributes to shortening the length (TTL) of the camera lens, but also promotes the relative illuminance.

In addition, the tables for each of the embodiments as follows correspond to the schematic views and the aberration graphs for each of the embodiments. The definitions of data in the tables are the same as those in Table 1 and Table 2 for the first optical embodiment. Therefore, similar description shall not be illustrated again. Furthermore, the definitions of element parameters in each of the embodiments are the same as those in the first optical embodiment.

The Second Optical Embodiment

As shown in FIG. 8, the camera lens may include seven lenses with refractive power, which are a first lens 11, a second lens 12, a third lens 13, a four lens 14, a fifth lens 15, a sixth lens 16, and a seventh lens 17 sequentially displayed from an object side surface to an image side surface.

Please refer to FIG. 8 and FIG. 9. FIG. 8 depicts a configuration diagram of the camera lens of the automobile identification system according to the second optical embodiment of the present invention. FIG. 9 depicts a curve diagram of the spherical aberration, astigmatism, and optical distortion illustrated sequentially from the left to the right according to the second optical embodiment of the present invention. As shown in FIG. 8, the camera lens includes a first lens 11, a second lens 12, a third lens 13, an aperture 60, a four lens 14, a fifth lens 15, a sixth lens 16, a seventh lens 17, an IR-cut filter 70, an image plane, and a first fingerprint sensor F1 or a second fingerprint sensor F2 sequentially displayed from an object side to an image side.

The first lens 11 has negative refractive power and is made of a glass material. The object side surface 111 thereof is a convex surface and the image side surface 112 thereof is a concave surface.

The second lens 12 has negative refractive power and is made of a glass material. The object side surface thereof 121 is a concave surface and the image side surface thereof 122 is a convex surface.

The third lens 13 has positive refractive power and is made of a glass material. The object side surface 131 thereof is a convex surface and the image side surface 132 thereof is a convex surface.

The fourth lens 14 has positive refractive power and is made of a glass material. The object side surface 141 thereof is a convex surface and the image side surface 142 thereof is a convex surface.

The fifth lens 15 has positive refractive power and is made of a glass material. The object side surface 151 thereof is a convex surface and the image side surface 152 thereof is a convex surface.

The sixth lens 16 has negative refractive power and is made of a glass material. The object side surface 161 thereof is a concave surface and the image side surface 162 thereof is a concave surface. Therefore, it may be effective to adjust the angle at which each field of view is incident on the sixth lens 16 to improve the aberration.

The seventh lens 17 has negative refractive power and is made of a glass material. The object side surface 171 thereof is a convex surface and the image side surface 172 thereof is a convex surface. Therefore, it is advantageous for the lens to reduce the back focal length to maintain minimization. In addition, it is effective to suppress the incident angle with incoming light from an off-axis view field and further correct the aberration in the off-axis view field.

The IR-cut filter 70 is made of glass and is disposed between the seventh lens 17 and the first fingerprint sensor F1, which does not affect the focal length of the camera lens.

As shown in FIG. 10, the camera lens includes a first lens 11, a second lens 12, a third lens 13, an aperture 60, a four lens 14, a fifth lens 15, a sixth lens 16, an IR-cut filter 70, an image plane, and a first fingerprint sensor F1 or a second fingerprint sensor F2 sequentially displayed from an object side to an image side.

The first lens 11 has negative refractive power and is made of a glass material. The object side surface 111 thereof is a convex surface and the image side surface 112 thereof is a concave surface, both of which are spherical.

The second lens 12 has negative refractive power and is made of a glass material. The object side surface thereof 121 is a concave surface and the image side surface thereof 122 is a convex surface, both of which are spherical.

The third lens 13 has positive refractive power and is made of a glass material. The object side surface 131 thereof is a convex surface and the image side surface 132 thereof is a convex surface, both of which are aspheric. The object side surface 334 thereof has an inflection point.

The fourth lens 14 has negative refractive power and is made of a plastic material. The object side surface thereof 141 is a concave surface and the image side surface thereof 142 is a concave surface, both of which are aspheric. The image side surface 142 thereof both have an inflection point.

The fifth lens 15 has positive refractive power and is made of a plastic material. The object side surface 151 thereof is a convex surface and the image side surface 152 thereof is a convex surface, both of which are aspheric.

The sixth lens 16 has negative refractive power and is made of a plastic material. The object side surface 161 thereof is a convex surface and the image side surface 162 thereof is a concave surface. The object side surface 161 and the image side surface 162 thereof both have an inflection point. Therefore, it is advantageous for the lens to reduce the back focal length to maintain minimization. In addition, it is effective to suppress the incident angle with incoming light from an off-axis view field and further correct the aberration in the off-axis view field.

The IR-cut filter 70 is made of glass and is disposed between the sixth lens 16 and the first fingerprint sensor F1, which does not affect the focal length of the camera lens.

(2) When the processor 10 determines that the sound information SF does not match one of the plurality of secondary reference sound information SSF, the person who attempts to enter the automobile C is not the user authorized by the driver to use the automobile C; the processor 10 does not obtain the use authentication and makes the door of the automobile C locked.

Similarly, when the processor 10 determines that the sound information SF matches one of the plurality of secondary reference sound information SSF, the processor 10 obtains the authorized use authentication, confirming that the person who attempts to enter the automobile C is the user authorized by the driver to use the automobile C; the positioning element 30 performs positioning for the automobile C and establishes a map according to the surrounding environment of automobile C; the positioning element 30 may also acquire the information on the weather and temperature of the place where the automobile C is located, and the user may better understand the environment and traffic; the user controls the operation of the peripheral element 40 through the human-machine interface 50; alternatively, the user may send a control signal to the wireless transceiver RT through an external electronic device, thus transmitting a control signal to the processor 10; the processor 10 controls the operation of the peripheral element 40 according to the control signal. Meanwhile, the processor 10 records the setting of the peripheral element 40 which is then stored as the user information UI of the database 20; when the driver sends the sound information SF to the sound sensor S again, the processor 10 may extract the user information UI from the database 20 according to the sound information SF; then, the processor 10 displays the user information UI on the human-machine interface 50.

In sum, the automobile identification system 1 of the present invention may obtain the first fingerprint image I1 and the second fingerprint image I2 through the first fingerprint sensor F1 and the second fingerprint sensor F2 disposed on the exterior and interior of the automobile C.
